Hard EEPROM reset
This utility allows you to reset the EEPROM inside the Printer. A hard
EEPROM reset is ONLY recommended when you need to install a used
Electronics Module in a different Printer. This is because there is a
discrepancy between the values of the Carriage EEPROM and the
Electronics Module EEROM and since the values of the Electronics Module
EEPROM are incorrect, a hard EEPROM reset will empty the Electronics
Module EEPROM. This will then force the Electronics Module EEPROM to
collect the values from the Carriage EEPROM when the Printer is next
powered up.
After a hard EEPROM reset, the Printer will act like a new
Prin
ter an
d try to prime the Ink Supply Tubes when the Printer
is next powered up.
Reset the EEPROM as follows:
1 Hold the pow
er button down and press the cancel button three times and
the resume button four times.
Hold Power Button
Press Resume button four times
Press Cancel
button three times
